Mn-Mn Dimers Induced Multimode Emitters in Mn-Activated AZn(PO) (A = K, Rb, and Cs) with Unique [ZnPO] Chains and [ZnO] Groups.

Mn-doped luminescent materials play a significant role in a variety of fields, including modern lighting, displays, and imaging. Mn exhibits a broad and adjustable emission, hinging on the local environment of the crystal field and the interaction of the 3d electrons. However, it is still a challenge to realize the precise control of the emission of Mn ions due to site-prior occupation in a specific lattice.

Exploring P-(Fe,V)-Codoped Metastable-Phase β-NiMoO for Improving the Performance of Overall Water Splitting.

It is especially essential to develop high-performance and low-cost nonprecious metal catalysts for large-scale hydrogen production. A large number of electrochemical catalysts composited by transition metal centers has been reported; however, it is still a great challenge to design and manipulate target electrocatalysts to realize high overall water-splitting activity at the atomic level. Herein, we develop totally new P-(Fe,V)-codoped metastable-phase β-NiMoO.

Unraveling the Role of Functional Groups of Terephthalate in Enhancing the Electrochemical Oxygen Evolution Reaction of Nickel-Organic Framework Nanoarrays.

The platelike nickel-terephthalate-type metal-organic framework nanoarrays (Ni-BDC NAs) on carbon cloth are obtained by employing agaric-like Ni(OH) NAs as sacrificial templates. The microenvironment of Ni-BDC NAs is modulated by various neighboring functional groups (-NH, -NO, and -Br) on the carboxylate ligand, exerting minimal destructive effects on the structure and morphology of Ni-BDC NAs. The electrochemical oxygen evolution reaction (OER) of Ni-BDC-NH NAs, Ni-BDC-NO NAs, and Ni-BDC-Br NAs exhibited a significant enhancement compared to that of Ni-BDC NAs alone, as evidenced by both experimental and theoretical assessments.

Simultaneous Induction of Immunogenic Pyroptosis and PD-L1 Downregulation by One Single Photosensitizer for Synergistic Cancer Photoimmunotherapy.

Pyroptosis, an excellent form of immunogenic cell death that can effectively activate antitumor immune responses, is attracting considerable interest as a promising approach for cancer immunotherapy. Immunogenic pyroptosis can recruit and stimulate dendritic cells to provoke further activation and tumor infiltration of T cells by releasing danger-associated molecular patterns, thus improving the tumor response to PD-1/PD-L1 checkpoint blockade immunotherapy. Here, we report the discovery of a bifunctional photosensitizer Nile Violet that can simultaneously trigger caspase-3/GSDME-mediated immunogenic pyroptosis and PD-L1 downregulation for cancer photoimmunotherapy.

Influences of gonad developmental stage on ovary selenium concentrations in fish-implications for ovary selenium monitoring.

Monitoring selenium (Se) concentrations in fish ovaries is an important tool for evaluating the ecological risk posed by Se in aquatic systems. Most guidance recommends sampling fish ovaries as closely as possible to when fish spawn on the premise that Se is mobilized from the liver to the ovary during vitellogenesis, and therefore, sampling ovaries during the early phases of oocyte maturation may underestimate egg Se concentrations at the time of spawning. In this study, we evaluated ovary Se data from two species with synchronous oocyte development (Ptychocheilus oregonensis and Prosopium williamsoni), one species with asynchronous oocyte development (Richardsonius balteatus), and one where the mode of development is unclear (Mylocheilus caurinus).
